Are you prepared for losing your phone? While away from home? I'm not sure that can be handled safely or at all in some cases. Have you considered it and if so what do you expect can be done to continue what you're doing until recovery can be completed? It sounds like you might have no ID and thus in many cases no authority to operate a vehicle, nor money/vouchers for travel much less necessities, and these days likely some or lots of trouble finding a way to communicate with anyone that may help. In some places some of that can be done with the help of strangers or police, but in others you could be ignored or worse. In some places driving without a license is not dangerous even if slightly illegal but in others you can find yourself incarcerated if nothing worse happens. My sister recently lost her handbag which made any attempt to operate her (work) vehicle a felony -- she was able to call the office due to the kindness of strangers so that an alternate driver could come out to deal with the vehicle (already on the shoulder) as well as giving her a lift back to her car which she then drove home (illegally) without incident; it was not a great experience.
Be sure to use an online type that always powers the output via the batteries, rather than a backup type the switches to battery after the input looks bad.
Choice? I don't use one but that's due to never exposing ports that don't need to be. Some that do that would still want one to provide "belt and suspenders". Others want a specific one vs another primarily due to the software they use, that others do not. Given how trivial it is to install one does it really matter? I'm fine if they do as long as it is easy to remove, i.e., not a critical system/global dependency. I always install and remove some anyway, don't you?
It's wonderful but can be less complete or even missing typically due to settings (e.g., security), the environment (e.g., a container), or both.
Keep in mind that you need backups perhaps moreso than you did when using OneDrive - 3-2-1 being robust without going crazy.
1.1.1.1 does no filtering. 9.9.9.9 does, similar to 1.1.1.2. To skip filtering use 9.9.9.10.
Anything will work as long as you encrypt first.
Hell I've seen 30 days. Sometimes they are using a third-party - it still should be almost immediate these days.
Fraud. It takes a while for them to receive the funds even though they are charged against your account almost instantly.
I expect they think that a significant percentage of people that have Internet also have a smartphone. They probably aren't far wrong.
Your OS might be killing (outright or effectively) your app - check dontkillmyapp.com for possible solutions. Or the app doesn't have notifications enabled at the app and system level.
What if you lose it? Do you have a plan?
